\VM. ALFRED GAY, OF BUFFALO, NEV YORK, ASSIGNOR OF ONE-HALF TO JOHN N. OULBERTSON, OF SAME PLACE.

SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 268,217, dated November 28,v 1882.

Application filed uly 31,1882. (No model.) d

To all whom it may concern:

Be it known that I, WM. ALFRED GAY, of the city of Bufit'alo,'in the county of Erie and State of New York, have invented a new and n eful Improvement in Sash-Holders, of which the following is a specification.

This invention relates to an improvement in a sash-holder, which consists of a plate ar ranged on the inner side of the sash, and provided with two bearing-surfaces which are inclined in opposite directions upwardly and downwardly, and a fixed screw or pin, which I is attached to the sash, and which operates against one or the other of said bearing-surfaces in such manner that said stud, screw, or pin, by pressing against one of said inclined bearing-surfaces, will wedge the plate against the window frame or casing, and thereby lock.

the sash either against upward or downward movement, as may be desired.

The object of my improvement is to so construct the holder that it can be readily adjusted to lock the sash against movement in either direction, or to permit the free movement of the sash, as may be required; also, to prevent the sash-holder from defacing the window-frame, and also to so construct the holder that the friction will be greatest between the plate and the window-frame and least between the stud, screw, or pin and the inclined bearing-surfaces of the plate.

My invention consists of the peculiar construction of the parts constituting the holder, which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figiire 1 is a side elevation of my improved sash-holder adjusted to lock the sash against upward movement. Fig. 2 is a side elevation of the sashholder adjusted to lock the sash against downward movement. Fig. 3 is a side elevation of the holder adjusted to permit the free movement of the sash in either direction. Fig. 4 is a vertical cross-section in line a: m, Fig. 2.

Like letters of reference refer to like parts in the several figures.

A represents the sash, and B the stationary frame or casing in which the sash moves.

0 represents the plate ofthe sash-holder, provided with bearing-surfaces d and d, which are inclined in oppositedirections, and which form the outer sides of an upright V-shaped slot, 1), formed in the plate 0.

E represents the straight bearing-surface of the plate 0, which rests against the frame or casing B, and which may be faced with a strip,

6, of rubber or other suitable material, whereby the friction between the plate 0 (which is preferably constructed of metal) and the frame or casing B is increased.

F represents a screw, which is secured to the sash A, and which passes with its outer portion through the slot D.

g is a sleeve or roller, which turns loosely upon the outer portion of the screw F in the slot D, and which rotates in contact with the inclined bearing-surfaces dd.

h is a washer, which is interposed between the head f of the screw and the plate 0, and which projects beyond the sides of the slot D 70, and prevents the plate 0 from becoming detached from the sash. If desired, however, the headf of the screw may be made large enough to answer this purpose, when the washer h is omitted.

1 represents an opening formed in the plate 0 at the apex of the slot D, between the latter and the frame 13. When the plate 0 is so adjusted that the upper portion of its slot D engages with the screw F, and an attempt is made to raise the sash, the screw F presses against the inclined bearing-surface d and forces the plate with its straight face E against the frame or casing B. The friction which is produced by this operation between the face E of the plate 0 and the frame or casing B prevents the sash from being raised. This operation is rendered more certain by the roller 9, which reduces the friction between the screw F and the inclined surface against which it operates, 0 so that the screw slides easily over the inclined surface and presses the plate 0 outwardly against the frame or casing B, the greatest friction existing between the face E of the plate 0 and the casing B, whereby the screw Fis 5 prevented from pushing the plate before it in the direction in which the screw moves. Upon adjusting the plate 0, so that the screw F bears against the lower inclined surface, (1, as shown in Fig.2, the sash is locked against downward no movement. Upon placing the plate 0 with the opening 1 upon the screw F, as represented in Fig. 3, the face E of the plate is held away from the casing, and the sash can be freely raised and lowered. The straight face E'ot' the plate 0 affords a firm bearing againstthe frame'or casing B, and serves to lock the sash securely in the desired position, while it does not deface the casing. The plate 0 is readily adjusted to lock the sash against movement in either direction, or to permit the free movement of the sash, and the parts operate freely and without injury to the locking device or the sash and inolosing frame.

I claim as my invention- 1. The combination, with a sash, A, having a screw, stud, or pin secured thereto, of a movable locking-plate, 0, provided with inclined bearing-surfaces d d, an opening, I, arranged between said bearing-surfaces, and forming a rest for the plate when not in use, and a straight face, E, adapted to bear against a stationary frame, B, substantially as set forth.

2. The combination, with a movable lockingplate, 0, provided with inclined bearing-surfaces d d, an opening, I, arranged between said bearing-surfaces, and a straight face, E, adapted to bear against a stationary frame, 13, of a pin, stud, or screw, F, secured to a sash, A, and a roller, arranged on the screw F to run in contact with said inclined bearing-surfaces, substantially as set forth.

WM. ALFRED GAY.
